Problems solved by technology

As the landing legs, the electric cylinder can accurately open the rocket landing device and provide support. In principle, the landing recovery can be realized. However, due to the heavy weight of the electric cylinder itself and the additional buffer device, the entire recovery landing device is cumbersome, which reduces the speed of the rocket. The carrying capacity, and the liquid rocket has higher requirements on the explosion-proof level of the electric cylinder

Abstract

The invention provides a launch vehicle and a multi-stage pneumatic support cylinder for recovering the launch vehicle. The multi-stage pneumatic support cylinder comprises a cylinder tube, a gas generator arranged in a mother cylinder tube and a buffer device arranged at an expansion and contraction part. The cylinder tube comprises the mother cylinder tube and a plurality of sub-cylinder tubes disposed together with the mother cylinder tube in a sleeved mode and disposed in the mother cylinder tube. The mother cylinder tube constitutes a fixed part of the cylinder tube, and the multiple sub-cylinder tubes constitute the expansion and contraction part of the cylinder tube. The multi-stage pneumatic support cylinder for recovering the launch vehicle has the advantages of safety, reliability and light overall weight, and can meet the requirements of rapid opening, supporting, shock absorption and righting correction of a rocket landing gear during use.

Description

technical field [0001] The invention relates to the field of aerospace, and in particular to a carrier rocket and a multi-stage pneumatic support cylinder for recovering the carrier rocket. Background technique [0002] At present, there are few rocket landing devices in China. Some of the existing landing devices use fixed outriggers, and some use electric cylinders as the landing outriggers. Fixed outriggers are only suitable for recovery tests, not rocket recovery landings. As the landing legs, the electric cylinder can accurately open the rocket landing device and provide support. In principle, the landing recovery can be realized. However, due to the heavy weight of the electric cylinder itself and the additional buffer device, the entire recovery landing device is cumbersome, which reduces the speed of the rocket. The carrying capacity, and the liquid rocket has higher requirements on the explosion-proof level of the electric cylinder. [0003] Therefore, how to prov...
